Tugas Pengolahan Citra Digital 1

1    A. Sampling : suatu proses mendigitasi koordinat objek. Proses ini memberikan   ukuran   citra (resolution pixel), misal : 10×10 pixel.

B. Kuantisasi (quantization) : suatu proses mendigitasi intensitas sinyal objek pada koordinat pixel yang disample, dengan kata lain member nilai pixel tersebut (penentuan intensitas warna/color depth), misal : nilai digital pixel =  0   1

 

2.  Colour depth

•        1 bit per pixel = 2 colours (monochrome)
•        4 bits per pixel = 16 colours
•        8 bits per pixel = 256 colours
• generally good enough for colour images 

•       16  bits per pixel = 65536 colours
• better quality for photograph like-images,also known as high colour 

•       24 bits per pixel = >16 million possible colours
• used to recreate photo realistic images,also known as true colour  monochrome)
